Title
(EN) ELECTRONIC CONTROL OF AGRICULTURAL VEHICLES
(FR) COMMANDE ELECTRONIQUE DE VEHICULES AGRICOLES
Abstract
(EN)
A method and apparatus for controlling a plurality of subsystems (66, 70) associated with an agricultural vehicle such as a tractor. Examples of such subsystems in a tractor are hitch positioning, power take off (PTO), multiple range transmissions, differential lock, diesel fuel injection, and the like. A unified control system is provided including a central control unit having a first microprocessor (56) and a plurality of subservient control units each having a microprocessor (58, 60). Each of the microprocessors (58, 60) of the subservient control units are connected for controlling at least one subsystem (66, 70) and for sensing the operating conditions of at least a single subsystem (66, 70) using sensors (68, 72). The subservient control unit microprocessors (58, 60) are also connected to the central control unit microprocessor (56), and microprocessor (56) controls communiication between the subservient control unit microprocessors (58, 60). Various control criteria, including desired relationships among various subsets of the conditions, are stored in memories associated with the microprocessors. The processors cycle through a series of subroutines in which various subsets of conditions are compared with the target, or desired relationships. Control signals are generated by the processors for controlling the individual subsystems to bring the conditions thereof to the targeted relationships. Such relationships include, but are not limited to engine advance characteristics as a function of engine RPM and torque, transmission shift points, criteria for over-riding a draft control for hitch positioning, and the like.

Procédé et appareil de commande d'une pluralité de sous-systèmes (66, 70) associés à un véhicule agricole tel qu'un tracteur. Le positionnement du dispositif d'attelage, la prise de force (PTO), les plages de transmission multiples, le verrouillage des différentiels, l'injection de combustible pour les moteurs diesel, et autres sont des exemples de ces sous-systèmes. Un système de commande unifié comprend une unité de commande centrale ayant un premier microprocesseur (56) et une pluralité d'unités de commande d'asservissement ayant chacune un microprocesseur (58, 60). Chacun des microprocesseurs (58, 60) des unités de commande d'asservissement est connecté pour commander au moins un sous-système (66, 70) et pour détecter les conditions de fonctionnement d'au moins un seul sous-système (66, 70) en utilisant des détecteurs (68, 72). Les microprocesseurs (58, 60) des unités de commande d'asservissement sont également connectés au microprocesseur (56) de l'unité de commande centrale, lequel microprocesseur (56) commande la communication entre les microprocesseurs (58, 60) des unités de commande d'asservissement. Divers critères de commande, y compris des relations désirées entre plusieurs sous ensembles de conditions, sont stockés dans des mémoires associées aux microprocesseurs. Les processeurs tournent sur une boucle une série de sous-programmes dans lesquels divers sous-ensembles de conditions sont comparés aux relations cibles ou désirées. Des signaux de commande sont générés par les processeurs pour commander des sous-systèmes individuels pour faire coincider leurs conditions avec les relations cibles. Ces relations comprennent, mais ne sont pas limitées aux caractéristiques d'avance du moteur en fonction du nombre de tours minute (RPM) et du couple du moteur, des points de changement de vitesse, des critères ayant priorité sur une commande d'attelage pour le positionnement de l'accrochage, et autres.
